Dear Tony, I am new to LTspice, and everyone is trying to help me with my query. You have put time in providing me solutions and so has Andy. I am thankful to both of you. You are again correct,

The rise and fall characteristics are only 2nd order effects - linear or exponential, it makes little difference. If you actually plot the derivative of the waveform, you get very pronounced spikes at

Dear Tony, Thank you for answering again. I believe I will have to finding the maximums and minimums localized to a specific time interval (example: 10 ms to 11 ms) and then do the rest. Your answer

Also, the comments in the two new uploaded files are somewhat misleading. "u" is always ASCII 0x75, when encoded with the normal ANSI character set. "?" is extended ASCII 0xB5, when encoded as a

That lacks backwards compatibility to anyone using an older version of LTspice.? (Yes, there are still some out there with old XP computers who do not wish to - or can't - upgrade to a newer

LTspice default will save schematic (*.asc) as ANSI ASCII file. uH or uF, the "u" is extended ASCII "0xB5", "mu" (?) to mean micro, see the glitching and comments,

Bouzid.wis, I am having trouble trying to understand how this circuit works. In the upper submodule, it seems like M1 can not do much, because C1 would charge and then not pass any more current, so

Using computer #1 today, so it is lowly LTspice XVII.? Not LTspice 24. You night have been hit by a yet-to-be-fixed bug - er, I mean side effect they added in version 24.1.x. Andy

That is a somewhat difficult question for me to answer.? Maybe others can speak to this better than I can. But I think the answer is "yes", I think it is normal. Because the waveforms are not

I think that problem goes away if you get rid of the UIC.? There is no need for UIC here.? Don't use it unless it is needed.? Change: .tran 0 100m 0 uic to: .tran 0 100m 0 or: .tran 100m or even

It should not be much larger than output current x output voltage/input voltage. That is, power out/input voltage. But I already told you that there is a very large inrush current because of the large

I don't know if this matters in your simulation, but you have started with much less than a sine wave.? 9 ms is less than one-half cycle of 50 Hz.? The output waveform does not seem right, however.

Remember to use English only in this group. Translation:? "I have uploaded the ltspice file under the name M2C single-phase SPWM112 to Temp" Note:? The actual filename is "M2C single phase

That is true, and it's something I often remind people about. Sure you could grab some random "90nm" model file and play around with it, but don't use it to model any actual circuits that you plan on

To be clear, Andy has found some *contributed* information, which is 5 years old. LTspice itself has no data on fabrication technology. My advice still stands; contact the foundry.

Good to know. As it must. How much is "too much"? So therefore it provides less than 500 W to the load, right? But some of that current into the primary represents reactive power, not rea

You get that from the foundry you plan to use to make your device. LTspice doesn't have that information. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

What version allowed the sim to run without stalling? I am now using 24.1.8, and the sim stalls after a different number of microseconds , depending on which tweak I have made to the .ASC.? I don't

Hello guys, Does anyone has 90nm CMOS technology text file or link something like that. Absolutely for LTspice.
